'Practice' in the Bible

But solid food is for mature people, whose minds are trained by practice to distinguish good from evil.

so that you will not be [spiritually] sluggish, but [will instead be] imitators of those who through faith [lean on God with absolute trust and confidence in Him and in His power] and by patient endurance [even when suffering] are [now] inheriting the promises.

Let love of your fellow believers continue.
